Warnings
Hazardous Voltages
The INPUT AND OUTPUT POWER connectors and cables of the SynQor MPS/MPPS may
have voltages that are unsafe. INJURY OR DEATH ON CONTACT may result. Appropriate
safety precautions should be taken. All connections should be made in accordance with
LOCAL ELECTRICAL CODES.
• The CHASSIS should be connected to earth or system ground with Ground Stud on the rear
panel, see mechanical diagrams.
• For the AC INPUT cable and connector:
▪ Do not assume that a hazardous voltage is not present at the terminals of the AC input
connector, even if the MPS/MPPS appears to be off.
▪ Do not make contact with the terminals of the AC input connector.
▪ Always connect the cable to the MPS/MPPS before it is connected to the source of AC power.
▪ Always disconnect the AC input cable from the source of AC power before disconnecting
it from the MPS/MPPS.
▪ If the AC input cable is connected to the source of AC power and not connected to the
MPS/MPPS, do not contact the exposed terminals of the AC input cable.
▪ Do not assume that the source of AC power is not present.
▪ Connections between the AC input cable and the source of AC power should not be accessible.
• For the MPPS DC OUTPUT cable and connector:
▪ The DC output terminals of the MPPS may be hazardous, depending on the model and user
commanded voltage. Never assume the terminals of the DC output connector or the wires
of the DC output cable are safe to contact, even if the MPPS appears to be off.
▪ The DC output terminals of the MPPS are isolated from the AC input with reinforced
safety insulation.
• For the MPS DC OUTPUT cable and connector:
▪ The rated DC output voltage of the MPS is below the level considered hazardous.
▪ The DC output terminals of the MPS are isolated from the AC input with reinforced
safety insulation.
▪ However, never assume the terminals of the DC output connector or the wires of the DC
output cable are safe to contact, even if the MPS appears to be off.
